I just found this on FHSWmans twitter! Looks like we are getting an armed Grasshopper!

He also posted this! It is an indigenous tank design from australia, the Sentinel! It was originally designed with a 2 pounder canon(40mm) but they also experimented with placing 17 and 25 pound guns on it to keep it up to date with late war tanks. It never saw action but maybe they will include it!
